Reactjs Maps without External Dependencies

Pigeon Maps - ReactJS maps without external dependencies

Demo: (using maps from OSM and Stamen)

What is it?

Are you tired of waiting 3 seconds to parse 200kb of Google Maps JavaScript just to display a few tiles and a marker? 140kb of minified Leaflet too much?

Welcome to the club!

This project aims to provide a performance-first React-centric extendable map engine.

It was originally created to reduce page load speed for the search results on Apprentus, a marketplace for private lessons.

We’re currently at:

  • minified
  • minified + gzipped


  • Show tiles
  • Arbitrary overlays (markers, etc)
  • Move the map by dragging
  • Move the map by touch on mobile
  • Zooming with the scroll wheel
  • Zooming by touch
  • Fractional zooming (e.g. to level 12.2)
  • Zoom without flickering (keep old tiles until new ones load)
  • Smooth animated zooming
  • Slide when dragging and letting go
  • Event handling (clicks, etc)
  • Double click and double tap zooming
  • Option to block dragging with one finger and mouse wheel scrolling without holding meta key
  • Enable/disable touch and mouse events as needed - you could make a 100% static server rendered react map
  • Support for 100% width/height containers


  • Double tap and then swipe touch zooming


One of:

# with yarn
yarn add pigeon-maps

# still on npm
npm install --save pigeon-maps


Demo (source)

import Map from 'pigeon-maps'
import Marker from 'pigeon-marker'
import Overlay from 'pigeon-overlay'

const map = (
  <Map center={[50.879, 4.6997]} zoom={12} width={600} height={400}>
    <Marker anchor={[50.874, 4.6947]} payload={1} onClick={({ event, anchor, payload }) => {}} />

    <Overlay anchor={[50.879, 4.6997]} offset={[120, 79]}>
      <img src='pigeon.jpg' width={240} height={158} alt='' />

Choose a tile provider

Note: If you’re getting 429 errors, it’s time to upgrade pigeon maps and choose a new tile layer provider. Versions before 0.15.0 use a default tile provider that no longer works.

Pigeon Maps defaults to loading map tiles from While free (thanks to volunteers and donations), these OSM tiles aren’t the best looking visually.

Usually you want to specify a custom map tile provider. There are many commercial tile servers to choose from and you can even set up your own.

One nice option is MapTiler. Their maps look good and their free plan provides up to 100k tile loads per month. You will need to sign up for an account and pass your API key and map id to the following provider

const MAP_ID = ''

function mapTilerProvider (x, y, z, dpr) {
  return `${MAP_ID}/256/${z}/${x}/${y}${dpr >= 2 ? '@2x' : ''}.png?key=${MAPTILER_ACCESS_TOKEN}`

    dprs={[1, 2]} // add this to support hidpi/retina (2x) maps if your provider supports them 

Adapt this example for other providers you might want to use.


pigeon-overlay (demo) - an anchored overlay

pigeon-marker (demo) - a simple marker component

pigeon-draggable (demo) - a draggable overlay

If you’re interested in making a new plugin, check out the code of pigeon-marker as a starting point. Feel free to clone the repo and rename every mention of pigeon-marker to pigeon-myplugin. You’ll get a demo and linking system out of the box. More documentation about this coming soon. Contributions welcome.



provider - Function that returns a TMS URL: (x, y, z, dpr) => url. The argument dpr will be a value from the dprs array (see below) or undefined when requesting the default tile.

center - Coordinates of the map center in the format [lat, lng]. Use if the component is controlled, e.g. you’ll be listening to onBoundsChanged and passing a new center when the bounds change.

defaultCenter - Initial coordinates of the map center in the format [lat, lng]. Use if the component is uncontrolled.

zoom - Current zoom level, e.g. 12, use for controlled components and update when onBoundsChanged give you a new value.

defaultZoom - The initial zoom for uncontrolled components.

width - Width of the component in pixels. Defaults to 100% of the parent div if not set.

height - Height of the component in pixels. Defaults to 100% of the parent div if not set.

defaultWidth - If you don’t specify a width, we wait until the component is mounted and measure the container before rendering tiles, markers and other objects. Setting defaultWidth assumes a width and renders everything before mounting. If the actual width of the component differs, it will just be re-rendered. Use this for example to render tiles on server rendering, when width is not set.

defaultHeight - Similar as defaultWidth, but for the height.

dprs - An array of devicePixelRatios that your tile provider supports. Defaults to []. Pass an array like [1, 2] and the numbers here will be sent to provider as the 4th argument. The responses will be combined into an <img srcset> attribute, which modern browsers use to select tiles with the right resolution.

animate - Animations enabled, true.

animateMaxScreens - If an updated center prop is more than animateMaxScreens screens away, we will directly switch to it, otherwise smoothly animate to it. Defaults to 5

zoomSnap - Snap to discrete zoom increments (14, 15, 16, etc) when scrolling with the mouse or pinching with touch events, Defaults to true.

minZoom - The lowest zoom level possible. Defaults to 1

maxZoom - The highest zoom level possible. Defaults to 18

attribution - What to show as an attribution. React node or false to hide.

attributionPrefix - Prefix before attribution. React node or false to hide.

onClick - When map is clicked `function ({ event, latLng, pixel })``

onBoundsChanged - When the bounds change, function ({ center, zoom, bounds, initial }). Use this for a controlled component, then set center and zoom when it’s called. This callback also gets called on the initial mount (when the first bounds become known). In this case the prop initial will be set to true. It will be false on all subsequent calls.

onAnimationStart - Called when the map starts moving

onAnimationStop - Called when the map stops moving

mouseEvents - Can the user interact with the map with the mouse? Defaults to true.

touchEvents - Can the user interact with the map by touching it? Defaults to true.

metaWheelZoom - Zooming with the mouse wheel only works when you hold down the meta (cmd/win) key. Defaults to false.

metaWheelZoomWarning - Warning text to show if scrolling on a map with metaWheelZoom enabled, but without the meta key. Defaults to Use META+wheel to zoom!, where META is automatically replaced with either “⌘” or “⊞”, depending on Mac vs non-Mac. Set to null to disable.

twoFingerDrag - Moving the map requires touching with two fingers. Defaults to false.

twoFingerDragWarning - Warning to show when twoFingerDrag and you try to move the map with one finger. Defaults to Use two fingers to move the map. Set to null to disable.

warningZIndex - The z-index value for the meta warning. Defaults to 100

boxClassname - The classname for the tiles div, allowing you to style it with a filter css property without impacting the overlays.


<Map /> takes random React components as its children. The children may have these special props:

anchor - At which coordinates [lat, lng] to anchor the overlay with the map.

offset - Offset in pixels relative to the anchor.

The children get passed these special props:

left - Pixels from the left of the map, calculated from anchor and offset

top - Pixels from the top of the map, calculated from anchor and offset

mapState - An object { center, zoom, bounds, width, height } that gets updated at every animation frame.

latLngToPixel - A helper function (latLng, center, zoom) that returns the position in pixels [x, y] for any [lat, lng]. The last 2 arguments are optional.

pixelToLatLng - A helper function (pixel, center, zoom) that converts any pixel coordinates [x, y] to [lat, lng]. The last 2 arguments are optional.

Use these two functions to create beautiful widgets. See a sample overlay.

Add the class pigeon-drag-block to disable dragging on the overlay. Add the class pigeon-click-block to disable map background clicks on the element.

Alternatively use the <Overlay /> component. It accepts anchor, offset and classNames as its props and positions itself accordingly.

Yeah, but why pigeon??

Pigeons are experts in magnetoreception. Good pigeons can find their way home from anywhere.

Magnets were essential in making the first maps. With a good map you can find your way home from anywhere.

Thus, pigeon.
